It will be interesting to see if the new Ford 7.3 gas V8 can match the fuel consumption of the old 7.3 powerstroke- not that it would take a huge feat of engineering. They must be looking for the halo effect in the truck market. The 6.7 powerstroke has also received some significant tweaks and should be more powerful than the current 450hp/930tq. Seems ridiculous, but everyone loves a powerful engine.
